Primal NPCs adds a new experience never before seen in a Human NPC mod. Players get the chance to interact and either make friends or enemies with NPC tribes.
You can chat to the NPCs using the chatbox there is a list of current chat commands on the roadmap.
NPCs bases are entirely procedural meaning every base is different. This includes external and internal structures.
Each NPC tribe has reputation that you can increase by offering a gift. You will unlock certain benefits like hiring dinos , equipment and requesting resources. You can also join the tribe or recruit the NPCs.

NPCs Spawn Automagically.
The wiki contains information about spawn codes & more detail descriptions of the mod.
There is a UI that you can view to see how many NPCs/Tames/Structures are on a map by pressing the F10.
This mod is best played on PvP with offline protection off.
If you dont see any NPCs in F10.. DestroyWildDinos will force them to spawn back faster.
